Stimulation of pain receptors in an internal organ that is also felt in another area of the body is called pain.

Fill in the Blank QuestionFill in the blank question.Sensory signals from the skin (i.e. touch, pressure, pain) are ultimately directed to the lobe of the cerebrum to an area called the somatosensory cortex.

What is meant by the term referred pain?Multiple ChoicePain felt in another body part due to misinterpretation by the brainPain due to overstimulation of mechanoreceptors of the skinChronic pain arising from overstretched musclesVisceral pain that is sensed as coming from another body part

The perception of pain:

What is the purpose of pain?Multiple choice question.to communicate when the body is being harmedto tell certain organs to shut downto turn off certain neural receptors

In order to sense pain, like stepping on a nail,  the signal needs to be relayed from the receptor in the skin to the neurons in the skin and then to the central nevous system.  This signal relay is an action potential.  Describe an action potential.  In your answer be sure to reference the four steps involved, the charges in each step, the movement of ions into and out of the nuron.  Also address which direction the action potential moves in the cell.
